Quick Answer

The Smart Export Guarantee (SEG) pays you for electricity you export to the grid from your solar panels. To qualify for SEG, your installation must be carried out by an MCS-certified installer. Without MCS, you cannot register for SEG and will lose your export earnings. We install through MCS-certified partners. Call 0141 230 0198.

The Smart Export Guarantee, or SEG, pays you for electricity you export to the grid from your solar panels in Scotland. To qualify, your installation must be carried out by an MCS-certified installer. MCS stands for Microgeneration Certification Scheme. Without it, you cannot register for SEG and will lose around two hundred to six hundred pounds per year. We install through MCS-certified partners. Call 0141 230 0198.
